Hi. All the books I read depict the electric fields and magnetic fields in electromagnetic waves as being in phase - meaning they reach their max or their min at the same time. The books also say that the changing electric field creates magnetic field and changing magnetic field creates...

For a molecule of water, I understand that there are 6 degrees of freedom for each of the three atoms within it; 3 translational and 3 due to the potential energy of the bonds. Is this at all affected when the water goes from solid to liquid or gas?

I understand that for H20 in solid form, each atom within the molecule has 6 degrees of freedom; 3 translational and 3 due to potential energy from bonds. Does the number of degrees of freedom change when water changes phase to a vapor?

To what level do most of you rely on your own handwritten class notes after the fact? I ask because I produce reams of paperwork, but can't imagine any of it ever being useful and am highly tempted to consign most of it to the bin. I would always go to a book on the subject before my notes if I...

HI , I don't know How to find a angle if the question is arc sin(6/25)+ 90 degree and also arc cos (-.2065) pls help

So I have a few different calculators I use. I am currently in a Calculus 1 and Physics 1 course. Both for engineers. As am example of what I am trying to explain, such as my physics HW It asked me to calculate the magnitude of the Vectors A+B+C. I do so and It worked fine, I did this is...

I was taking notes in class and the prof said that in the equation y^(double prime)-3y^(prime)+2y = 0 that 2 was the order.. is that due to the following? the first y = 0 when you take the derivative twice the second y = 0 when you derive it once and the first one = 2 when you derive it...

To study for a M.B.A. in Accountancy, M.S. in Computer Science and Engineering, and a PH.D. Theoretical Physics/Physical Chemistry? And obtain those degrees? How long would it take?

hey, I am wondering if anyone knows of any universities in europe (excluding the UK) which offer bachelor degrees in physics that are taught in English, perhaps with an inclination towards theoretical physics? There must be a few of them around, but I'm not aware of any! I do know of a few...

Hi all, I am currently in the last year of high school, and currently I am considering what faculty to enter in University.. most likely Engineering or Computer Science, because the admission average for Science is way too high for me. I am mostly interested in physics, math, and computers. I...

I'm not trying to sell you one! :biggrin: While having a coffee, I just read this interesting article in an old issue of Symmetry: http://symmetrymagazine.org/cms/?pid=1000304 We all get these emails offering degrees but I never thought that so many people would buy them, or obtain jobs with...

Math Graduate Schools: Views on undergraduate degrees Hello How do graduate schools look upon students who receive a B.A. and a B.S? I am planning to do a dual degree with Columbia University, getting a B.A. in math/economics, and a B.S. from Columbia. I then want to go for a PhD in applied...

Hello everyone, I am thinking of going abroad to get a masters (or an equivalent) and then try to get into a U.S. grad school for my Ph.D. I was wondering whether this is a good idea in itself, i.e. perhaps many U.S. schools think that M.Sc. is for people who aren't strong enough for Ph.D., is...

Hello everyone, I need help with converting or changing degrees to radians in Microsoft Excel. Currently I'm writing SIN and COS functions but the default angles are in degrees, not radians. How do I format it to radians?

Functions that "introduce" new degrees of freedom? OK, I realize this is a wacky question, so forgive me! BUT I was thinking about it the other day, and suppose I had a 2 dimensional space \Bbb{R}^{2}. Is there any function that generally exists as: f: \Bbb{R}^{n} \rightarrow \Bbb{R}^{n+1}? So...

When reading in the web about decoherence especially in popular articles I find very often explanations that point out the fact that the environment has a large number of degrees of freedom. It is unclear to me in which extent and in which aspects this is relevant for decoherence. My...

I'm sure most people are familiar with the 6 degrees of Kevin bacon game. Here's something for folks to have fun with. The rules are: 1) You must name 2 relatively well known celebreties who have both appeared in at least one theatrical movie (i.e., not made for TV nor TV series). 2) You...

Out of pure curiosity, I'd be very interested to find out what degrees members have and in what subjects. Also, what you wrote for your dissertation to get your degree (s). I'm not yet finished school, so I haven't experienced university life. I know that I want to study geography, and get a...

Does anyone know why there is 360 degrees in a circle? Why not 100 for simplicity sake?

For the purposes of this thread LQG is defined in a pragmatic unrigorous way. Loop gravity is what loop gravitists do. That begs the question who are representative loop gravitists? Well it is a fuzzy set but I think we all have an idea who they are: people like Rovelli, Smolin, Freidel...

Anyone know of any specific colleges that offer degrees in one or both? I haven't seen many with degrees in Particle Physics. Thanks!

Having suffered strong depersonalisation and varying degrees of derealisation with anxiety for a month, I'm wondering if the depersonalised state is the highest and most critical state of being one can experience. I'd love to hear the experiences of others with this state.

Angular momentum is a vector, so alegedly it has 3 degrees of freedom. It has never been formally told me, but I noticed angular momentum is taken as two separate magnitudes and not three. i.e. in quantum mechanics there's an operator for \bf{L}^2 and for L_z and this should be enough. My...

So this is where I've been hiding all week. The first two days it was in the upper 50s and I skiied in a t-shirt under my ski jacket shell. On the 4the day (Wednesday), it was 11 at the top of the mountain and snowing. The snow was nice, but we couldn't see bcause it was snowing so hard...

I am refreshing my maths and came across this formula stated as a fact without explanation in a geometry text. How does this work? I would have thought (mod 2Pi) was the decimal portion of 2Pi but that doesn't multiply out to 180. Thanks, R.

Im a first year mechanical engineering student, and I think that I would like to do work with particle accelerators (beam physics and technology). Does anyone have any recommendations as to what specific degree(s) I should look into, and which schools have great programs? Thanks!

Yea it's almost deadline time to pick a college for me... Picking a college that has a good program seams important. And I'm not too sure what major would be best to pursue. I have thought about various Engineering degrees but mostly Engineering Physics or just Physics, but I'm not too sure what...
